Hello and Welcome to Neurotalk, Cherylal - you will meet many great and supportive people here!!
I'm sorry to hear that your cousion suffers from RSD and seizures

. I have RSD in my left leg and right arm - I developed it when I was 12 years old after an ankle sprain, I am now 13. If I can help you in anyway, please just let me know, I know how scary it can be dealing with this sort of horrible illness!
Take care and please send your Cousion my best wishes and give her a pain-free hug from me! I look forward to seeing you around the forum and in the Chatrooms soon!!
Alison
